Application filed November 16,1896- Serial No. 612,390. (No model.)

To aZZ whom it may concern.-

Be it known that I, GUSTAF ADOLF GRISELL, a citizen of the United States, residing at Madison, in the county of Dane and State of \Visconsin, have invented certain Improvements in Machines for Forming Armature- Coils, of which the followingis a specification.

My invention relates to formers or machines for forming coils for arm atu re-winders.

The object is to provide a machine which shall be susceptible of all the various and necessary transformations or arrangements of the several parts, so as to permit coils of any size and shape to be formed thereon, at least so long as they are of the general nature of the coils illustrated in the drawings.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a perspective view of the 1nachine with a coil shown in dotted lines. Fig. 2 is a section on the line 2 2 of Figs. 1 and Fig. 3 is a section on the line 3 3 of Fig. 2. Fig. 4 is a View of the coil.

Like parts are indicated by the same letters in all the figures.

A is the bed-plate, having at one side the upwardly-turned flange B. This flange is provided with a slot C, through which passes the bolts C, having the inner heads C and the outer thumb-nuts C These nuts are preferably provided with holes C into which a nail or pin can be put so that they can be turned. On the inside of the flange B there are a series of slides D, having each a vertical slot D, through which passes the bolt C, and a flange D which comes down in opposition to the top of the flange B, and an upper face or flange E. On each of the pieces D is mounted an angle-iron F, having a slot F, through which passes the bolt F having the head F on one side and the thumb-11ut F on the other side. Each piece D has an offset Gr, through which pass two adj Listing-screws H, the upper ends of which bear against the lower extremity of the slotted angle-piece F. The upper portion of the angle-piece F overhangs and opposes the surface or flange E just as the flange D overhangs the top or upper surface of the flange part B. All of the pieces D rest upon the bar J,which in turn rests upon the screws JJ, which are threaded into the bed-plate A. The bed-plate A is provided with two slots K K, through which project the screws K K. Each of these screws has a head K which is received in the T-shaped slot in the cross-bar K and such screw has a thumbnut K at its outer extremity and a bearingplate K between the nut and the bottom of the bed. On top of each of the cross-pieces K is placed a standard K", having a downwardly-projecting part to be received into the upper neck of the T-shaped slot in the bar K and adapted to slide along it.

L is a bolt having the head L, which projects into the slot, and the nut L which engages the projection on the standard. This standard is shaped as shown, having the upper table M forming part of a circle. It has a vertical oblong slot therethrough, into which drops the shank N, associated with the circular flange-like part N. Two holes N are formed through these parts, and down into them the screws N N are let, being screwthreaded into the shank portion and bearing against the upper surface of the bar K The several portions of the coil are indicated as follows: The longer straight portion of the wires is marked 0, the shorter straight portion P, the flattened end portions R and S, respectively, and the terminals T. The bolts M pass through the standards K and the shanks N, connected with the parts N. The shank N is slotted at M so as to allow the plate or part N to be removed when the bolt is loosened. The plate l and the shank N may be held in place by means of a nut or similar deviceas, for example, by means of the cam -lever M This lever when used takes the place of the nut, the parts being bound together by moving the lever in one direction and loosened by moving the lever in the opposite direction.

The use and operation of my invention are as follows:

In the effort to form a coil such as is indicated in the drawings, particularly in Fig. l, a good deal of difficulty is experienced because the coils have to be formed quite accurately and with smoothness and regularity. Moreover, the coils have to be varied in size Lil and shape frequently to accommodate the different styles of machines, and in view of the different kinds of wire used, and in View of the variations in the castings of machines of substantially the same size and form. Moreover, in the economical employment of workmen it is necessary that a workman should pass from the making of one kind of coil to another at comparatively frequent intervals. These several circumstances, together with others, call in shop practice for a machine which shall be entirely general for the manufacture of coils, so that any sort of coil within the limits suggested may be made upon any machine.

To vary the form of the part 0 of the coiland its size will be determined by the number of wires, the number of layers, and the thickness of the wire used-I loosen the nut F' and raise or lower the angle-bar by adjustin g the screw II, and then clamp the parts in position again by operating the nut I Thus by having a series of these angle-bars I can determine at will the arrangement or form of the part 0. If this part is to be varied, so as to be entirely straight or set at an angle to the part P of the coil, I may raise or lower either of the pieces D by loosening the nut C and raising or lowering the bar J at either end by means of the screws J J.

I can determine the length of the parts P by bringing the pieces D close together or removing one or more of them entirely, the remainin g ones being locked in proper position by the bolt 0. To determine the thickness of the part P of the coil, I may raise or lower the part or parts D, again setting such part in position by operating the nut C Turning now to the remainder of the coil, it is clear that if the parts 0 P are to be lengthened or shortened the parts R and S must be brought nearer together or separated farther from each other, as the case may be, and this can be done by loosening the nuts K and moving the bars K toward or from each other and then tightening the nuts again. It may also be desired to lengthen that portion of the coil which extends from O or P to the middle of the part R or S or to shorten the same. This is accomplished by moving the standards K along the bars K the same being loosened or locked in position by operating the nuts L on the bolts L whenever required. The thickness of the parts R and S being dependent upon the number of layers and the gage of the wires used is determined by operating the screws N thus raising or lowering the part N with reference to the part M. hen the parts are all in proper position, the coil is wound thereon by carrying it successively about. For instance, beginning at one end, I may carry a single wire around between the parts F and E, then between one of the sets of parts M and N, then back between the parts B and D then back around the other set of parts M and N to the starting point, whence the circuit is contin ued until the coil is completed. The table may be supported on a proper standard, for which I have left a hole in the middle of the bed A. To remove the coil, it is necessary to release the plate N from its engagement with the standard, which is done by means of the handle. The plate N can then be lifted off, whereupon the coil can be easily removed from its position. It may then be properly taped or coated, as the case may be.

I do not wish to be limited to the precise construction of these several parts, as some of them can be used without others while yet containing the substance of my invention, and many of them, if not all, may be more or less modified without departing from the spirit of my invention.

It will be noticed that the several forming parts are arranged in different horizontal planes and that they are also arranged in different vertical planes, the two sides of the coil when in position being in different hori zontal and also in different vertical planes.
